Stack Solidification Status

Date: 2026-05-09

Hygiene refresh: 2026-05-10

Bottom Line

The stack is buildable and internally gateable, but not promotable as a live hardware-accelerated system yet.

Full Lean/Semantics build: SKIPPED
JSON integrity: PASS
Python shim compile: PASS
Support receipt refresh: PASS
Rainbow Raccoon compiler: PASS_WITH_HOLDS (1 candidate, 6 HOLD)
Tri-cycle audit: PASS; promotion decision NO_PROMOTION
FPGA software witness: PASS
FPGA hardware witness: NOT_REQUESTED
UART beacon seen: False
Hardware bitstreams present: PASS
Optional sem entity-diff aid: OPTIONAL_AUDIT_AID_READY
RRC HOLD closure checklist: PASS_ALL_ITEMS_CLOSED (0 open; compiler rerun still required before promotion)
Network HOLD manifests: PASS_HOLD_QUEUES_DECLARED (9 coefficient rows, 15 prediction rows)
Beaver mask freshness controls: PASS_NEGATIVE_CONTROLS (6 cases)
Whitespace-zero grammar: PASS_ZERO_WHITESPACE_CANONICAL (3 admitted, 3 HOLD)
Q16 virtual serial probe: PASS_VIRTUAL_SERIAL (3/3 matches)
UART transport routes: PASS_ACTIVE_VIRTUAL_ROUTE (active virtual://q16-pty)
Stack fail closure register: PASS_TICKETS_DECLARED (7 tickets)
SMN tool awareness: PASS (ADMIT_SMN_TOOL_AWARENESS)
Worktree: DIRTY
Staging manifest: 6-Documentation/docs/stack_solidification_staging_manifest_2026-05-09.md

Lean/Semantics builds end to end.
Core JSON receipts and network topology database parse.
Compiler gate admits only the Q16 fixed-point lowering certificate as candidate.
Q16 software witness lane passes.
Q16 host UART framing and parser pass over a PTY-backed virtual serial device.
UART route table now selects the PTY-backed Q16 route while keeping blocked physical routes visible.
HOLD buckets are explicit rather than silently promoted.
Optional sem entity extraction is available for scoped Python audit files.
SMN is tool-visible as Semantic Mass Number and explicitly separated from Mass Number admissibility packets.
Every compiler HOLD object now has an explicit closure checklist, and the RRC Gatekeeper has closed 11/11 documentation closures.
Current failures and broad HOLD buckets have closure tickets in a stack fail register.
Network topology coefficients and predictions are split into HOLD queues.
Beaver mask freshness has Lean-backed finite negative controls; full MPC security remains HOLD.
Canonical logogram grammar can derive ordinary spaces from symbol count/order with zero stored whitespace codes.
Agent routing now has repo-root, Lean/Semantics, and Infrastructure contracts.
Stack receipts and the network topology database are visible through narrow .gitignore exceptions instead of broad shared-data/ exposure.

Live FPGA UART transport remains blocked: beacon receipts show no bytes on /dev/ttyUSB0 or /dev/ttyUSB1.
Hardware acceleration claims remain blocked until the UART route or external adapter path produces matching receipts.
Security, coefficient, topology-prediction, and receipt-gate debts remain HOLD surfaces.
The worktree is broad and dirty; do not stage by directory sweep.
/usr/bin/sem is GNU Parallel on this machine; use the isolated sem binary path if sem is needed.

Resolve fabric UART transport with board bridge docs or an external USB-UART adapter.
Work the closure register tickets in order: UART transport, flash persistence, adaptive-mask security, coefficient calibration, topology predictions, receipt gates, then worktree scope.
Rerun the Rainbow Raccoon compiler against the refreshed closure receipts before changing any HOLD/CANDIDATE status.
Produce a scoped staging manifest before any commit because the working tree contains many unrelated/generated surfaces.
